I'm pretty sure this tracklist just gets sadder and sadder, ending with one of the most gut-wrenching kpop songs I can think of: Jaejoong's All Alone.
I tried to attach all the versions with english translations so that everyone can see just how sad some of these songs are. Kpop is so much more than catchy choruses and cute dances.
Hyorin & Jooyoung - Erase
GD and Jennie Kim - Black
Lee Hi - Because
Epik High - Umbrella
